LOREN GRANT JACKSON, OF WOODMAN, WISCONSIN, ASSIGNOR OF ONE- HALF TOOSCAR M. L OOMIS, OF SAME PLACE.

POTATO-DIGGER.

SPECIFICATION forming part of Letters Patent No. 330,898, dated November24, 1885.

Application filed July 1, 1885. Serial No. 170,371.

To all whom it may concern:

Be it known that I, LOREN G. JACKSON, a citizen of the United States,residing at Woodman, in the county of Grant and State of WViscousin,have invented a new and useful Improvement in Potato-Diggers, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to an improvement in potatodiggers; and it consistsin the peculiar construction and combination of devices that will bemore fully set forth hereinafter, and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of apotato-digger embodying my invention, the near wheel being removed. Fig.2 is a top plan view of the same. Fig. 3 is a detailed perspective viewof the digger.

A represents the axle, to which is secured the rear divided end of thetongue 13, which forms the frame, a transverse beam, 0, being securedbetween the rear divided ends of the tongue, which extend a slightdistance beyond the rear side of the axle, as shown. A transverse bar,D, is secured to the tongue at a suitable distance from and in front ofthe axle, said bar being secured on the under side of the tongue, and onthe upper side thereof, in rear of the bar D, is a transverse beam, E. Aspring-standard, F, is secured to the center of the axle, and carriesthe drivers seat G. Slotted standards H depend from the ends of the barD, and similar standards, I, depend from the rear divided ends of thetongue, the standards H being braced, as shown.

K represents a hand-lever, that is journaled on one end of the beam E,and has an arm, K, bent at right angles, and L represents a similarhand-lever journaled on the rear end of the frame diagonally oppositethe hand lever K, and having a bent arm, L.

The scoop or digger M is composed of the curved fingers m, which aresecured at the proper distance from and parallel to each other on atransverse bar, m. To the outer 0f the fingers are bolted the curvedbeams 012?, which extend through the slotted standards H and I, and aresecured together by trans- (No model.)

verse bars m, journaled in the braces W. This scoop or digger issuspended below the frame by straps m, which connect the bars in withthe bent arms K and L of the handlevers. Transverse bolts or pinsm arepassed through the forward extended ends of the beams m and bear againstthe front sides of the standards H, and sustain the draft of tliedigger. Rack-segments N are provided on the frame, and the hand-leversare provided with springactuated bolts 0, to engage with the racks andhold the levers at any desired position. Sup porting-wheels P arejournaled on the ends of the axle in the usual manner. By means of thehand-levers the digger or scoop can be caused to run in the ground atany desired depth or to be raised out of the way when in transportationand not in operation. The transverse bars m form fulcrunrpoints for thebeams of the digger. By means of the levers K L either the front or rearend of the digger may be raised or lowered, and thus in cline the diggerto any desired angle. By this construction perfect adjustability isprovided for the digger, and it is thereby rendered capable of beingadjusted so as to run in the ground at any desired angle or at anydesired depth. As the machine moves along, the digger uprootsthepotatoes, and as they move rearwardly over the digger they are clearedof adhering earth and roots and deposited on top of the ground.

A potato-digger thus constructed is exceedingly light, cheap, andsimple, is thoroughly practical in operation, and is not likely to getout of order.

Having thus described my invention, I claim- 1. In combination with theframe and the levers, the digger or scoop composed of the 2. Thecombination of the frame having the,

levers K L and the depending slotted standards H and I with the scoop ordigger having thecurved parallel fingers, and the side In testimony thatI claim the foregoing as beams, m working in the slotted standards, myown I have hereto affixed my signature in the transverse bars mjournaled in the beams, presence of two witnesses.

and the links W, connecting the said bars- LOREN GRANT JACKSON. 5 withthe levers, whereby the scoop or digger Witnesses:

may be raised or lowered at either end, sub- J. MOLAUGHLIN,

stantially as described. HENRY R. FLORY.
